Can flowers understand language?

 ANSWER: Some flowers can.

The expression 해어화 (解語화) literally means "an understanding (解) language (語) flower (花)," which means "a flower that understands language." The 해 (解) in 해어화 (解語화) is the same 해 used in 이해하다 (理解하다), which means "to understand." The expression 해어화 was and, I guess, still is used to describe a beautiful woman as a talking flower.
